@aayushidianapps ,
Thank you for posting to the PayPal Sandbox Community.
The error message "Things don't appear to be working..." is a generic error message. Here are the main reasons that you may be receiving this error message:
Merchant Trying to pay themselves, this is considered cash advancing a restricted activity
Incorrect Variable
Variable with special characters like " or $ in them
Setting on the account
Email being used in integration not added or confirmed on your PayPal Account
If you provide the merchant id for your sandbox business account, I can make certain that it has a confirmed email address, as well as review the settings associated with it.
Here is how to find your merchant id in your sandbox business account:
Log into the sandbox business account at https://sandbox.paypal.com
Go to Account Settings
Click on Business information
PayPal Merchant ID will display
Thank you,
